Supervisors

What made you decide to supervise? I’m a younger GS 14 (non/sup) and would like to promote to at some point. Should I stay in this job for the next 20 plus years or try to promote to a non-sup 15. I know there aren’t a whole lot of options for a non-sup 15. I could supervise, but it doesn’t seem that desirable as I’m looking at what some managers have to deal with. Thought?
